CVE-2026-72649— Deserialization of Untrusted Data in Elasticsearch Leading to Remote Code Execution

Quick assessment

Affected
Elastic Elasticsearch
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Elasticsearch 机器学习组件中存在的不可信数据反序列化漏洞（CWE-502）可能导致通过对象注入（CAPEC-586）实现远程代码执行。一个特制的已训练模型工件可能触发由攻击者控制的逻辑执行，且其系统调用权限范围远超预期。利用该漏洞需要拥有足够权限以创建和部署已训练模型的经过身份验证的用户。

Vulnerability Title
Deserialization of Untrusted Data in Elasticsearch Leading to Remote Code Execution
Source: CVE Program / CVE List V5
Vulnerability Description
Deserialization of Untrusted Data (CWE-502) in the Elasticsearch machine learning component can lead to remote code execution via Object Injection (CAPEC-586). A specially crafted trained model artifact could cause attacker-controlled logic to execute with a materially broader system-call surface than intended. Exploitation requires an authenticated user with sufficient privileges to create and deploy trained models.
